Show Hidden Files Issue

Show Hidden Files Issue / Problem (due to Virus) •

Open registry( select run command from start menu and type regedit and then press enter)

•

In the left pane goto path HKEY_LOCAL_MACHINESoftware\Microsoft \Windows \CurrentVersion \Explorer \Advanced \Folder \Hidden \SHOWALL

•

Delete the value CheckedValue in the Right pane by right clicking it and selecting delete. (Its type should be REG_SZ and data should be 2.)

•

Create a new DWORD value called CheckedValue by right clicking in the Right pane and then selecting new -> DWORD Value and then changing the name to CheckedValue. (same as above, except that the type is REG_DWORD). Modify the value data to 1 (0×00000001) by right clicking the CheckedValue in the Right pane and selecting modify and changing the value data to 1.

This should let you change the “Hidden Files and Folders” option. Why this happens? The fact that the hidden files were not showing up was due to virus which would have changed the value in the registry and the virus may be still present. Even when the virus was removed the old value may not have been restored in the registry.
